My mania stopped in less than a week...but it was a short term solution
You can drink a little alcohol while taking carbamazepine, but it could make you very sleepy
- You can continue to drink alcohol while taking carbamazepine but having the two together might make you very sleepy.
- If you drink a lot of alcohol, however, it could increase the carbamazepine level in your body, and this could be dangerous.
- So, during the first few days, it might be best to stop drinking alcohol until you see how the medicine affects you.
- If you want to drink alcohol, remember that you might be sleepy and make sure you can get home safely.
Do not drive a car or ride a bike just after you start taking carbamazepine
- Taking carbamazepine may make you feel sleepy or dizzy, and may affect your eyesight, when you start taking it.
- This could affect you if you drive a car, ride a bike, or do anything else that needs a lot of focus. It might be best to stop doing these things for the first few days, until you know how it affects you.
- Do not worry - most people do these things as normal while taking carbamazepine.
Try not to take carbamazepine for the first time just before your exams
- You could feel dizzy, restless or confused when you first take carbamazepine, and it could affect your eyesight.
- You should talk to your doctor about any future exams if you are starting carbamazepine.

Carbamazepine is not a banned substance in sport

Carbamazepine does not mix well with street drugs
- Cannabis and carbamazepine do not seem to have an effect on each other. Using both at the same time might make you feel more sleepy.
- Carbamazepine reduces the level of methadone in the body when they are used together, so if you stop carbamazepine your methadone level might go up dangerously – talk to your doctor about this before you stop carbamazepine.
- Carbamazepine drives cocaine break down to make more norcocaine. This chemical is more dangerous to your heart and liver than cocaine itself

Let your family and friends know you are taking carbamazepine so they can support you and help you look out for side effects
- The side-effects of carbamazepine might put a strain on your friendships and relationships, especially in the first few days of taking it.
- You might feel restless, anxious, restless, aggressive or low.
- These side-effects should get better after a few days.
- You should then be getting the good effects of carbamazepine, and that should improve your relationships in itself.

- They could look at the medicine leaflet, or at this website.
- They could help you to understand whether the medicine changes your behaviour, or gives you side-effects (sometimes it is hard for us to see it ourselves).
Carbamazepine can have side-effects that might affect your sex life
The good effects of carbamazepine may have a good effect on your sex life as your symptoms settle and you can concentrate on your relationships.
- There are some possible side-effects that include:

- Not wanting to have sex as much
- Spotting and bleeding between periods for women
- Difficulty in getting an erection (impotence) for men
- If you get a skin reaction, acne or hair loss, you may not feel as sexy as before
These effects should pass after the first couple of weeks. If they do not, and this is a problem for you, go back to the doctor and see what else you could try.
